Google has yet to give us any real detail about what the Android update will actually contain. No, we're not expecting four fingers of wafer in the Nexus 5, but it's triggered a run of promotional activities from Nestle, which will be offering Android devices as prizes and so on. The Nexus 5 was spotted in the KitKat statue unveiling at Mountain View.
